The 5 Beneficial Actions of
L. casei strain Shirota
Reaches the Intestines Alive
Ten healthy adults were given a probiotic drink containing over 10 billion L. casei strain Shirota over a period of four weeks. The number of LcS in the feces was investigated.
The L. casei Shirota strain does not succumb to the gastric juices or bile. It reaches the intestines alive.
Increases Beneficial Bacteria
Ten healthy adults consumed a probiotic drink containing over 10 billion L. casei strain Shirota over a period of four weeks. The change in intestinal microbiota* was investigated.
*Intestinal microbiota refers to the microorganisms, including bacteria, that live in our intestines.
L. casei strain Shirota increases the bacteria in the intestines that have a beneficial action on people.
Reduces Harmful Bacteria
Ten healthy adults consumed a probiotic drink containing over 10 billion L. casei strain Shirota over a period of four weeks. The change in intestinal microbiota* was investigated.
*Intestinal microbiota refers to the microorganisms, including bacteria, that live in our intestines.
L. casei strain Shirota has been shown to reduce bacteria that are harmful to the body.
Improves the Intestinal Environment
Seven healthy adults consumed a probiotic drink containing over 10 billion L. casei strain Shirota over a period of five weeks. The urinary indican content was investigated.
It was confirmed that L. casei strain Shirota had the effect of reducing harmful substances*.
* The presence of indican was measured. Indole, one of the harmful substances produced by intestinal bacteria, is changed in the liver and is excreted in the urine as indican. Indole has a potentially carcinogenic effect.
Regulates the Condition of the Intestinal Tract
Forty slightly constipated people were divided into two groups. One group consumed a probiotic drink containing 40 billion L. casei strain Shirota while the other group consumed a placebo* containing no L. casei strain Shirota. Both groups consumed one drink per day for two weeks, and their bowel movements were investigated during the two week period.
Thirty healthy people with slightly loose, more than regular bowel movements were divided into two groups. One group consumed a probiotic drink containing 40 billion L. casei strain Shirota while the other group consumed a placebo* containing no L. casei strain Shirota. Both groups consumed one drink per day for four weeks, and their bowel movements were investigated.
*A placebo has the same taste and appearance but does not contain any active ingredients.
L. casei strain Shirota helps to keep the intestinal tract in good working order in cases of loose stools as well as in cases of constipation!
